Yahoo! chief Marissa Mayer wants Microsoft's Bing to deliver

Yahoo Inc Chief Executive Marissa Mayer said the company's search partnership with Microsoft Corp was not delivering the market share gains or the revenue boost that it should.

"One of the points of the alliance is that we collectively want to grow share rather than just trading share with each other," Mayer said at the Goldman Sachs Technology and Internet Conference in San Francisco on Tuesday.

In her first appearance at an investor conference since taking the reins of the struggling Web portal in July, Mayer said she planned to prune a sprawling lineup of mobile apps and she reiterated her focus on enticing consumers to spend more time on Yahoo's online properties, in order to display more money-making ads.
